Specification of Letters latent.

Application filed February 11, 1905. Serial No. 245,311.

To all whom it may concern:

Be it known that I, Eoenn'r H. GOLD, a citizen of the United States, residing at Chicago, in the county of Cook andState of Illinois have invented certain new an useful Improvements in Interchangeable Heating Systems, of which the following is a specification.

My invention relates to improvements in heating systems in which a suitable heating medium is caused to traverse a circulating system.

My invention relates more particularly to improvement in that type of heating system which is shown and described in my Patent No. 758 45363 and which, while suitable for use in various situations is particularly adapted and intended for use in railway car heating, especially where the various cars of a train are heated by a heating medium such as steam which is supplied by a common generator such as the boiler of a locomotive.

A particular object of my present invention is to provide a heating system of the type shown in my said Patent No. 7 58,486, which may be quickly and readily converted into a high pressure heating system having direct connection to the high pressure supply, and in which the thermostat, which forms a part of the controlling device when the system is used as a low pressure system, becomes a part of the automatic trap for permitting the discharge of the water of condensation when the system is converted.

into a high pressure system.

These and various other objects are attained by my invention which are more specifically pointed out in the hereto annexed claims.

Typical my present invention are shown in my aceompanying drawings Figure 1 shows in perspective and dia gramatically a car heating plant.

Fig. 2 is an enlarged vertical section through the combined controlling device and steam trap.

Fig. 3 is a horizontal sectional detail. on

and convenient embodiments of the line 88 of Fig. 2 looking in the direction indicated by the arrows.

Fig. 8 is a vertical section of a modified embodiment of my invention.

Fig. 9 is an enlarged sectional detail.

Fig. 10 is an enlarged detail shown in perspective.

Like characters of reference indicate the same parts in the several figures of the drawings.

Referring to the accompanying drawings which show my invention applied to a car heating system, but without limiting myself thereto A indicates the train pipe which conducts steam under high pressure from the locomotive. B is the feed pipe which leads from the train pipe to the hand valve C, which in turn connects with the controlling device E through the pipe D. From the controlling device E steam flows through the pipe F through the radiating pipes G, H, and back through the return I into the controlled device E and thence through the blow-off J which extends through the floor K to the diaphragm casing L and thence to the atmosphere.

Referring now to Fig. 2, it will be seen that steam from the pipe D enters the inlet chamber 2 of the casing E through a port 1, which port 1 is controlled by a valve 3 provided with guide wings I and adapted to engage a valve seat 5 upon a nipple 6. Passing through the inlet chamber 2, the steam flows out through the pipe F and after passing through the radiating system returns through the pipe I into the outlet chamber 7 of the casing E. The outlet chamber '2 communicates through a port in Patented Mar. 24), 191?.

the nipple S with the blow-off pipe J which leads to the diaphragm chamber 9 in the casing L and thence to the atmosphere.

Suitably mounted within the diaphragm chamber 9 is an expansible diaphragm 10 adapted to actuate a stem 11, said stem being rotatingly mounted in a button 12 which rests upon the upper face of the diaphragm. Upon that portion of the stem 11 which extends into the outlet chamber 7 is threaded a collar 13 provided with an upwardly extending sleeve 13 When the collar 13 is adjusted at its upward limit the sleeve 13 abuts against a shoulder or collar 14; which is secured to the stem 11 and thus constitutes a stop to limit the upward adjustment of the collar 13.

A yoke 15 on one end of a lever 16 is ar ranged in operative engagement with the collars 13 and 141. This lever 16 is rigidly secured to a spindle 17, which, as shown in Fig. 1 extends through a stuffing box 18 into the inlet chamber 2 and the end of the spindle 17 which projects into the inlet chamber 2 has rigidly secured thereto a lever'arin 19, provided at its end with ayoke 20 which surrounds stem 21 of the valve 3.

Said stem 21 is provided with a collar 22 above the yoke 20, the valve 3 constituting a collar upon the stem 21 below the yoke 20.

As so arranged and with the parts adjusted as shown in Fig. 2 it is obvious that the expansion of the diaphragm 10 which results whenever the circulating pipes are filled with live steam so that it overflows into the diaphragm chamber 9, will lift the stem 11, whereupon the collar 13 engaging the yoke 15 will lift the arm 16 causing a partial rotation of the spindle 17 and a cor responding depression of the arm 19 and closure or partial closure as the case may be of valve 3.

Whenever the diaphragm 10 becomes cool and correspondingly contracts, the stem 11 will drop of its own weight and the collar 14 contacting with the voke 15 will depress the arm 16 causing the arm 19 to rise and to lift the valve 3 from its seat, thus permitting afresh inflow of steam from the train pipe. 7

It will be recognized that with this ad justment of the parts the resulting operation will be substantially that described in my Patent No. 758,436.

Now continuing the description of my apparatus, 23 is a valve threaded on to the stem 11 below the valve seat 28 which is formed on the lower end of the nipple 8. This valve is provided with wings 24:, shown more clearly in Fig. 3, which slidingly engage vertical guides 24 Secured to the stem 11 below the lowermost adjusted position of the valve '23 is a valve 23 and the collar 26 is a packing ring 27 which may be conveniently used but is by no means necessary in the ordinary use for car heating. 29 is a key extending through a stufling box 30 and rotatably mounted upon the casing E. It is internally squared so as to operatively engage the correspondingly squared end 31 of the stem 11.

With the parts adjusted as shown in Fig. 2, if the hand wheel 32 on the key 29 be turned in the direction of movement of the hands of a clock, the stem 11 will be rotated, but since the collar 13 is held against rotation by guide wings 13 which engage guides E (wide Figs. 5 and 6) the collar will be caused to descend on the stem 11, and the valve 23 which is also held against rotation will be caused to rise on the stem 11 until the valve 23 tightly clamps the packing ring 27 against the collar 26 and thus is brought to the limit of its upward adjustment while at the same time making a tight joint between the valve 23 and the collar 26.

With the parts in such newly adjusted position, as is shown in Fig. 7 the collar 13 is so far below the yoke 15 and the valve 23 has been moved upwardly upon the stem 11 such a distance, that when the diaphragm 10 is caused to expand, the valve 23 will be seated against the seat 28 before the collar 13 can be raised far enough to bring it in contact with the yoke 15. Consequently the lever arms 16 and 19 will be disconnected for all operative purposes from the dia phragm 10 and the inlet valve 3 will remain wide open. The valve may be held open in any convenient manner or the pressure of steam from the train pipe may be relied upon to hold the valve 3 in open position. Consequently the pipes of the heating system will become filled with steam at train pipe pressure and temperature.

\Vhenever the diaphragm 10 cools sufliciently to perceptibly contract, the valve 23 will open, accumulated water'of condensation will be discharged and as it is followed by live steam, the diaphragm 10 will expand and the valve 23 will again close, although in actual practice it will be found that the valve 23 will remain open just enough to permit, water of condensation to escape as the steam condenses, but without permitting connections whereby the escape of any considerable quantity of steam.

l' i henever the rotation of the hand-wheel 32 is reversed the valve 23 will descend so as to no longer contact with the seat 28 while collar 13 will simultaneously rise until the sleeve 13 abuts against the collar l l, restoring the collar 13 to operative relations with the yoke 15.

In Fig. 8 I have shown a modified construction in which the collars l3 and 14: are united by the sleeve 13 so that when the rotation of the hand wheel causes the collar 13 to descend, the lever arm 16 will be positively depressed and the lever arm 19 will be correspondingly extent that the inlet valve will be held so far away from its seat that the expansion of the diaphragm and the corresponding elevation of the stem 11 will be insufficient to close the inlet valve.

lVhile l have shown a convenient and per ha ps preferred embodiment of my invention, many departures may be made therefrom as a matter of convenience, mechanical skill or shop expediency, and my invention contemplates all such changes in form which come within the scope of the appended claims.
